It is designed for repeatable, automated, and declarative cluster management. + +### Key Features + +- **Declarative VM Provisioning:** Proxmox VMs for control plane and worker nodes are managed via Terraform. +- **Talos OS & Kubernetes Versioning:** Talos and Kubernetes versions are parameterized in `variables.tf` for easy upgrades. +- **Automated Cluster Configuration:** Talos machine configurations are generated and applied automatically to each node. +- **Rolling Upgrades:** Change a version variable and apply to safely upgrade Talos and/or Kubernetes across your cluster. +- **CI/CD Linting:** A GitHub Actions workflow automatically checks Terraform formatting and lints code on pull requests and pushes to `main`. + +### How to Upgrade Talos or Kubernetes + +1. Edit the version variables in `variables.tf`: + ```hcl + variable "talos_version" { + default = "v1.9.5" + } + variable "kubernetes_version" { + default = "1.32.0" + } + ``` +2.
